I've been experimenting recently with using my own images with Debris, trying to make a composite of a whole lot of photos of my dog to print up and give to my ex as a gift.

I understand I can drop images on to the Debris window to add them to the "Downloaded image files" part of the Debris processing, but I'd like to serve my images from a HTTP server, on which I've written a script to randomly resize a random image from my own directory of images.

My script works fine, and I can save a whole lot of images randomly generated by it and drop them on to the Debris window to have them added to the composite, but I can't use the "image download url" configuration of Debris to go get them.

I would like Debris to continually get a new random image from this location and hence continually composite these images on top of one another. Even though they are all variations in the size of a group of say 20 images, there will be continuous variation in the combination of these images and I can just pick out a nice lookin Debris to print up.

I've written the script to (i) randomly select an image then (ii) to randomly resize it and then (iii) to serve as a JPEG directly to a browser:

Reload to randomise the URL (which does nothing but trick Debris into thinking that it's a different image).

I've tried both of these URLs in Debris' "Source" URL field, but Debris simply hits this URL every 19 seconds, adding 1 to the "Urls in url cache", but never downloads any images (or use any on the canvas). I've even made a little page with many links and many embedded images (i.e. IMG tag), still no result.
